Just on a technicality, your 12th image in the sequence demonstrates that you've got the wrong field sequence order set up in your original interlaced video sequence. You've got a frame made from field 2 of frame N then field 1 of frame N+1 (rather than field 1 and field 2, both from the same frame), hence the two ghostly images appearing together. (It must have been taken on a cut.) There may be a choice of 'field dominance' or 'field sequence' in your editing software that needs changing to the other value.
